“The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1800 square feet (167 square meters) of floor space, weighed 30 tons, consumed 160 kilowatts of electrical power. There was even a rumor that when turned on the ENIAC caused the city of Philadelphia to experience brownouts, however, this was first reported incorrectly by the Philadelphia Bulletin in 1946 and since then has become an urban myth.”

And that’s where the term bug had it’s genesis. A moth got into one of those early beasts with all the tubes and caused some problems. A computer bug.
I’ve been around computers for a couple of years. First one I worked on was a Sperry Univac 1219B missile fire control digital computer, with a whopping 32KB core memory.
